2006 Pontiac Grand Prix

Offered for sale is a striking 2006 Pontiac Grand Prix GXP, a performance-oriented sedan that represented the pinnacle of the Grand Prix lineup in its era. This particular example is a two-owner Grand Prix, has covered only 37,366 miles since new, and is finished in an elegant Stealth Gray Metallic exterior paired with an Ebony interior featuring leather-appointed seating. As the most powerful factory-built front-wheel-drive Pontiac of its time, the GXP stands out with engineering, design, and equipment that set it far apart from the more common V6 and GTP models, making it an especially sought-after variant among enthusiasts. While GM did not record production numbers by trim, it is widely believed that GXPs were produced in significantly lower quantities than their six-cylinder counterparts, adding to their exclusivity.

At the heart of the GXP is the 5.3-liter LS4 V8 engine, delivering an impressive 303 horsepower and 323 lb-ft of torque. This all-aluminum small-block was the first V8 offered in a Grand Prix since 1987 and the first Pontiac equipped with Displacement on Demand (DOD) technology, allowing the engine to seamlessly deactivate four cylinders under light load for improved fuel efficiency. Engineered specifically for a front-wheel-drive layout, the LS4 features a shortened crankshaft, a compact accessory drive, and optimized packaging to fit transversely in the Grand Prix chassis. Coupled with a Hydra-Matic 4T65-E four-speed automatic transmission with TAPShift manual shift control, the GXP delivers strong, confident acceleration and responsive performance while offering the driver fingertip gear selection when desired.

The GXPs handling package was tuned to match its power, with Bilstein gas-charged struts, higher-rate springs, a reduced ride height, and a 17.2-mm hollow rear stabilizer bar for sharper turn-in and reduced body roll. One of the GXPs most distinctive engineering touches is its staggered wheel setup 18-inch polished forged aluminum wheels with wider fronts than rears a configuration designed to improve front-end grip, stability, and braking performance. Bringing it to a stop is a high-performance four-wheel disc brake system with vented and cross-drilled rotors paired with aluminum calipers and twin-piston front units for strong, fade-resistant braking. Magnasteer II variable-effort steering and StabiliTrak stability control further enhance driver confidence.

This example is equipped with the $1,015 Premium Package, which adds dual-zone automatic air conditioning, leather-appointed bucket seats with UltraLux suede inserts, a flat-folding front passenger seatback, and heated driver and passenger seats for added comfort. Also included is the $3,285 Sun and Sound Package, which features a power sunroof and the Monsoon premium speaker system, delivering an enhanced audio experience. The drivers seat is six-way power adjustable with power lumbar support, ensuring personalized comfort behind the wheel.

The cabin reflects the GXPs performance character with GXP-specific instrument gauge faces featuring an engine-turned metal appearance, brushed aluminum-style door sill plates, and thoughtful driver-oriented controls. A notable highlight is the Heads-Up Display (HUD), which projects key driving information into the drivers line of sight, including gear position when in TAPShift mode, enhancing both convenience and focus. The layout is driver-centric, with a curved center stack angled toward the driver and straightforward climate and audio controls.

With its distinctive styling, advanced engineering, rare V8 powertrain, and two-owner history, the 2006 Pontiac Grand Prix GXP delivers an engaging driving experience and stands as a unique chapter in Pontiacs performance heritage. This low-mileage example, finished in Stealth Gray Metallic with an Ebony leather-appointed interior, combines exclusivity, performance, and desirable factory options in
